GSM/GPRS Quad band TTL UART modem (SIM800C) - rhydoLABZ

GSM/GPRS Quad band TTL UART modem( SIM800C) from rhydoLABZ, is built with Quad Band GSM/GPRS engine- SIM800, works on frequencies 850/ 900/ 1800/ 1900 MHz. The Modem comes with selectable interfacing voltage, which allows you to connect 5V & 3V3 microcontroller directly without any level conversion chips. The baud rate is configurable from 9600-115200 through AT command. The GSM/GPRS Modem is having internal TCP/IP stack to enable you to connect with internet via GPRS. It is suitable for SMS, Voice as well as DATA transfer application in M2M interface.

The Modem is manufactured with Automatic Pick and place machine with high quality standard. The onboard Low dropout 3A Power supply allows you to connect wide range unregulated power supply (5V-12V). Using this modem,you can make audio calls, SMS, Read SMS, attend the incoming calls and internet etc through simple AT commands.

Note: Featuring an industry-standard interface and tiny configuration of 35mm x 50mm x 3 mm, GSM/GPRS Quadband TTL/UART modem SIM800C can fit almost all the space requirements in all applications, especially for slim and compact demand of design.
